摘要:

受早期关于重建包含暗能量分量的修正引力模型的工作的启发,我们考虑了新提出的(m,n)型全息暗能量模型,并将其推广到两种修正引力模型f(R)和f(T)理论,其中R和T分别代表Ricci标量和挠率标量.具体来说,我们重建后两个重力模型,并讨论其可行性和宇宙学。所得到的引力模型是无鬼的,与当地的太阳系测试兼容,并描述了有效的正引力常量。

英文摘要:

Motivated by earlier works on reconstruction of modified gravity models with dark energy components, we extend them by considering a newly proposed model of (m, n)- type of holographic dark energy for two models of modified gravity, f(R) and f(T) theories, where R and T represent Ricci scalar and torsion scalar respectively. Specifically we reconstruct the two later gravity models and discuss their viability and cosmography. The obtained gravity models are ghost free, compatible with local solar system tests and describe effective positive gravitational constant.
